Hello Rob and Jay,

Many thanks for the reports and all the det= ails. Jay, did you miss the 22 UTC transmission or did it not decode?<= BR>Interesting to see the phase plots. It is expected that the phase i= s less stable when the band opens. In the last transmission, the Eb/N0= is not high enough to see the phase pattern.
I wonder if the trace= s become more evident if 4K19 is used.

What happens when a sola= r event happens during the transmission time? Does it change the phase= or just the D layer attenuation?
Maybe we can repeat the experimen= t, using 4K19A. Of course a carrier could be used too, but i like to '= play' with EbNaut.

So, tonite:

Hi LF,=

Just a short EbNaut message tonite. I'm interested to see the= phase changes on a long path. Markus's showrawsyms does a good job th= ere, as long as 8K19A is used. A shorter message should also help to b= uild up a clear trace.
